CLEVELAND -- During his interrogation with police, the man accused of kidnapping and raping three women said he was addicted to sex and could not control his impulses, Channel 3 News has learned.

Calling himself "cold blooded," Ariel Castro led police with exacting detail through the days that he abducted Michelle Knight, Amanda Berry and Gina DeJesus, from how he met them to what they were wearing that day, sources told the Investigator Tom Meyer.

Castro was ordered held on $8 million bond today by a Cleveland Municipal Court judge.

Meanwhile, in a suicide note discovered in his house by police, Castro blamed the girls for their abductions, writing that they were the ones who got into his car in the first place, sources said.

He also mentioned his sex addiction, as well as having previously endured physical abuse as a child in the note.

None of the abductions seemed planned, the sources said. Rather, they appeared to be crimes of opportunity.

Castro believed he would eventually be caught because he did not have "an exit plan" on how to deal with the three women and the girl he held captive in his Seymour Avenue home, the sources said.

He just did not think it would be so soon.

In fact, Castro told police they had a chance to arrest him at one point but they missed him, the sources said. It is unclear when that was.

Cleveland Police knocked on Castro's door in 2004 to investigate a case in which Castro, a Cleveland school bus driver, left a child in his bus.

A year later, in 2005, a Cuyahoga County Sheriff's Deputy went to the home three times in an attempt to deliver a court summons.

Castro appeared to be "cocky" during the interview and the only remorse that showed was over his capture, Channel 3 News was told.

In the suicide note, Castro did write that he wanted to give his money and possessions to the women if he was caught, the sources said.

The note appears to have been written in 2004 about the time when police were investigating him over the bus incident.
